Stopping and restarting Yate

While running the following signals and keys are trapped and used:

 - SIGTERM and SIGINT (Ctrl-C) will cleanly stop the engine
 - SIGHUP and SIGQUIT (Ctrl-\) will reinitialize the modules

If you have rmanager module you can also connect to port 5038 and use "stop" to stop the engine, and "reload" to reload the configurations.

Note that the modules are not reloaded, only their configuration files are read. Also note that some modules have options that are read only on the first initialization.

If Yate is started in supervised mode (command line option -s) it can also be restarted from rmanager using "stop 128" - in fact any code between 128 and 255. The program will be stopped cleanly then the supervisor will restart it with the same command line options.
